I've been working on this for 30 min

Step 1: Y is equal to so where ever you see a y in the equation 3x - 4y = -5 replace it with

3x - 4() = -5

Now all your variables are x and you can solve for x

Step 2: Distribute for to the numbers in the parentheses

3x - 3x - 8 = -5

Step 3: Combine like terms

0x - 8 = -5

0x = 3

Step 4: Isolate x

0x/0 = 3/0

3/0 is undefined

^^^ This means that there is no answer

If you look at the graph below you can see that these lines are parallel and therefore have no intersection point

Hope this helped!

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.
